[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] RE: Eliminating duplicate nodes
Thanks for the help. I thought it made perfect sense, but I'm still have
a couple issues. I have tried to give a simpler example that maybe you
could help me with...
I know this xml document structure doesn't make much sense, but I just
made it this way to show what I am trying to do. So, I want to display
the content of all nodes which have a unique id.
So, in the example
<records>
<contact id="0001">
<title id="mr">Mr</title>
<forename id="john">John</forename>
<surname id="smith">Smith</surname>
</contact>
<contact id="0001">
<title id="othermr">Mr</title>
<forename id="otherjohn">John</forename>
<surname id="othersmith">Smith</surname>
</contact>
<contact id="0002">
<title id="dr">Dr</title>
<forename id="amy">Amy</forename>
<surname id="jones">Jones</surname>
</contact>
<contact id="0003">
<title id="dr">Dr</title>
<forename id="amy">Amy</forename>
<surname id="jones">Jones</surname>
</contact>
</records>
...this would display:
Smith,
John (Mr)
Smith,
John (Mr)
Jones,
Amy (Dr)
Notice that although the first 2 'contact' nodes have the same id, I
want to traverse inside them.
Here is what I'm using now, but it doesn't do what I want:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version='1.0'
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
<xsl:key name="contacts-by-surname" match="*" use="@id" />
<xsl:template match="*">
<xsl:for-each select="*[generate-id() =
generate-id(key('contacts-by-surname', @id))]">
<xsl:value-of select="surname" />,<br />
<xsl:value-of select="forename" />
(<xsl:value-of select="title" />)<br /><br />
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Thanks so much!
-Mac

Subject: Re: Eliminating duplicate nodes
I don't see any grouping code. But here is an example:
Add this <xsl:key/> as child of <xsl:stylesheet/> to your XML document:
<xsl:key name="elements" match="*" use="concat(name(), '::', @id)"/>
Change all your <xsl:apply-templates/> to the following:
<xsl:apply-templates select="*[generate-id() =
generate-id(key('elements', concat(name(), '::', @id)))]"/>
Maybe you don't need the name() in the grouping condition. It's for
differing between <element1 id="foo"/> and <element2 id="foo"/>. If
these two elements should count as "duplicate" change
"concat(name(), '::', @id)" simply to "@id".
Furthermore you have to add some special handling to these
<xsl:apply-templates/> for elements without any @id. Maybe they should
be processed in every case. Then simply change it to:
<xsl:apply-templates select="*[not(@id)] | *[generate-id() =
generate-id(key('elements', concat(name(), '::', @id)))]"/>
And what's with text nodes? Maybe a third change:
<xsl:apply-templates select="text() | *[not(@id)] | *[generate-id() =
generate-id(key('elements', concat(name(), '::', @id)))]"/>
> <xsl:for-each select=".">
> <xsl:apply-templates />
> </xsl:for-each>
That's not meaningful. Change it simply to <xsl:apply-templates/>. The
<xsl:for-each/> iterates over all current nodes - which can only be one,
as the name says the currently processed node.
